ABB 2CSF204197R1250 F204 A-25/0,03 400Hz RCCB A 4-pin 25 A 0.03 A 400 V

Residual current protective devices (RCCBs) offer personal and property protection as well as protection against electrically ignited fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. The F200 series residual current circuit breakers provide protection for sinusoidal alternating currents and pulsating currents with smooth DC residual current of up to 6 mA against earth. They comply with the product standards IEC/EN 61008-1, 61008-2-1, 61543. Applications include commercial and industrial applications, e.g. in industrial networks with 200 Hz or 400 Hz. The extensive range of accessories offers you everything was needed for your installation tasks. Advantages: Increasing the frequency increases the magnetic resistance of the toroidal current transformer of standard RCCBs. As a result, the value of the rising operating error current at 400 Hz reaches values that are three times or many times greater than the values of the fault current at 50 Hz. The RCCB F200 400 Hz guarantees fault protection (protection against indirect contact), additional protection (with IΔn ≤ 30 mA), when one considers that the operating fault current does not increase with the line frequency.
